The hazards of management-controlled nonroutine work in the process areas must be communicated to affected individuals. The work permit prescribes the procedures that must be followed to get the permit. Work authorization procedures specify lockout/tagout, line breaking., confined space entry, and hot work authorization through clear steps leading to job completion, closure, and return to normal. 

If, during the ignition sequence or the running sequence, flame failure occurs, a lockout will result, which will require manual resetting.

The valve was operated by compressed air, and the two air hoses, one to open the valve and one to close it, were connected up the wrong way around. The two connectors should have been different in size or design so that this could not occur. In addition, they were not disconnected, and a lockout device on the valve—a mechanical stop—had been removed. It is also bad practice to carry out work on equipment isolated from hot flammable gas under pressure by a single isolation valve. The take-off branch should have been slip-plated, and double block and bleed valves should have been provided so the slip-plate could be inserted safely (Figure 1-1), [16, 17]. 

There was another similarity to the first incident. In this case the equipment also had been prepared for repair and then had to wait for a couple of days until the maintenance team was able to work on it. During this period, the air lines were reconnected, the lockout removed, and the isolation valve opened. 

The accidental or unexpected sudden starting of electrical equipment can cause severe injuiy or death. Before ANY inspections or repairs are made (even on the so-called low-voltage circuits) the current should be turned off at the switch box and the switch padlocked in the OFF position. At tlie same time, the switch or controls of the macliine or other equipment being locked out of service should be securely tagged to show which equipment or circuits are being worked on. Lockouts and tagouts should be removed only by the individual(s) who installed them. 

Turn off power to electrical equipment before tests and repairs tlien lock and tag it out so it does not turn on by accident. Follow your company s lockout/tagout procedures.

No work should be attempted until the boiler has properly cooled down, all safety and shut-off switches are in the off position, and all lockout and tagout procedures have been followed. 

The boiler doors and openings are closed, properly gasketed, and sealed. All protective sheets and covers are removed. Lockouts and tagouts are removed, and finally the unit is inspected before firing-up recommences. 

Many postoperative patients require less narcotics when they are able to self-administer a narcotic for pain. Because the self-administration system is under the control of the nurse, who adds the drug to die infusion pump and sets the time interval (or lockout interval) between doses, the patient cannot receive an overdose of the drug.
